SMOKE-CONSUMER.

SPECIFICATION formingpart of Letters Patent No. 643,110, dated February 13, 1900..

Application filed September 20, 1899. Serial No. 731,077. (No model.)

To (I/ZJ whom it may concern:

Be it known that I, JOSEPH F. CODY, a citizen of the United States, residing at Peoria,

in the county of Peoria and State of Illinois,

have invented certain new and useful Improvements in Smoke-Consumers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in smoke-consumers, by means of which a very effective device is provided for the purpose.

More particularly, my invention relates to means adapted to produce a jet or flame and project the same into the combustion-chamber or fire-pot in such a manner as to cause an effective combustion of the smoke before it leaves the fire-pot.

My invention consists, essentially,in the combination of ducts and pipes adapted to bring together the necessary elements to produce a jet or flame and the detailed manner of arranging the parts to produce the best results.

That my invention may be more fully understood reference is had to the accompanying drawings in which- Figure 1 is a front elevation of a portion of a boiler, showing my device connected therewith. Fig. 2 is a vertical section through the fire-pot, also showing the manner of applying my device. Fig. 3 is a detailed view of parts of my device.

In the drawings, A represents the boiler, which is supported just above the fire-pot, which is constructed in the usual manner, as indicated in the drawings.

B is a cold-air duct across the boiler-front and is supported in the hangers b b and is open at both ends and throughout its entire length.

O, O, and C together with the couplings c c, constitute a duct leading from a point at the rear portion of the ash-pit and near to the grate to the cold-air duct.

D D, as shown in Fig. 3, are dischargepipes, connected with and opening out of the cold-air duct B. These pipes extend into the fire-pot, as shown in Fig. 2, and D is an exhaust-tube. In carrying out the invention any number of such pipes may be provided as may be found necessary to best accomplish the work in connection with any kind of boiler and fire-pot, and they may project into the fire-pot any distance desired.

' E E are steam-pipes leading from the boiler and are provided with cut-off valves 6 e.

E is a steam-pipe connected with steampipes E E, which is carried through cold-air duct B.

e and c as shown in Fig. 3, represent fanjet tubes connected with and opening out of steam-pipe E, as at e and 0 the said tubes being carried within the larger pipes D D and are flattened at their outer ends in the manner shown in Figs. 2 and 3, and are so flattened as to provide for the discharge of a wide thin jet of steam, which thus formed and discharged best facilitates in the operation and carrying out of the purposes of my invention.

In carrying out the invention itis purposed to provide a series of discharge-pipes, as D, connecting with and opening out of the coldair duct B in the manner shown, as at b, and projecting forwardly into the fire-pot, each of said ducts to contain the fan-jet tubes (2 e Alongside of said pipes D and D there are designed to be placed similar pipes, as D connected with the cold-air duct B in the same manner as at b and in numbers and location to best facilitate in operating the device. In the burning of fuel in the fire-pot the smoke is the result of imperfect combustion. In course of combustion only a portion of the fuel on the grate is consumed, and if perfectly consumed no smoke would be produced; but perfect combustion upon the grate is impossible, so that in the process of combustion the unconsumed particles of coal rise and produce what is callec smoke, also carbonicacid gas is liberated.

In the operation of myinvention I seek to employ the gases generated or produced in combustion in connection with steam and cold air to produce a flame, and by bringing said elements together in a proper manner and at a proper point I am able to produce a flaming jet or a series of flaming jets above the burning fuel on the grate that will intercept and completely consume any smoke resulting from imperfect combustion on the grate.

The mechanical operation of the device is as follows: Steam from the boiler passing through pipes E E and E is discharged through fan-jet tubes 6 e in wide thin jets, and the force of-suchdischarge causes a suction in discharge-pipes D D, which causes cold air to be drawn through cold-air duct B into discharge-pipes D Dand discharged out and around the steam-jets from tubes 6 6 The draft through the cold-air duct B into the pipes D D will cause a suction through the exhaust-tubes D which will draw the hot gases from the upper portion of the combustion-chamber into the cold-air duct and thence will be discharged through dischargepipes D D mingled with cold air, and this mixture will be mingled with the steam from fan-jet tubes as the mixture is discharged into the combustion-chamber.

I may employthe duct leading from a point below the grate and connecting cold-air duct, if desired; but ordinarily it is not my purpose to use the same, as the device will ordinarily work as well without its use; but if used the hot-air duct therefrom is merely an aid and is discharged in the same manner as the hot air and gases from the exhaust-ducts D The combustion of these elements thus discharged into the fire-pot produces a highly inflammable gas which readily ignites and produces flaming jets, and the force of the projected steam carries said jets deep into and far across the upper portion of the fire-pot, there being as many of such jets produced as there are pipes combined as D and e and D and 6 and as the result of the flame-jets being projected into the fire-pot all of the smoke that rises from combustion on the grate is completely and effectually consumed.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a smoke-consumer, the combination with a furnace or fire-pot of a cold-air duct open at both ends, a series of discharge-pipes as D D, opening out of the same and comm unicating with the fire-pot, steam-pipe E carried within said cold-air duct, fan-jet tubes as e and 6 carried through the dischargepipes and communicating with the fire-pot and draft duct or ducts as D communicating with said cold-air ductand also com municating with said fire-pot, all substantially as described and shown.

2. In a smoke-consumer, the combination with a combustion-chamber or fire-pot of a series of discharge-pipes communicating with said fire-pot, a cold-air duct open at both ends communicating with the discharge-pipes, a steam-pipe carried within said cold-air duct and a series of fan-jet tubes opening out of the steam-pipe and carried through the discharge-pipes, and an exhaust tube or tubes communicating with the combustion-chamber and the cold-air duct and arranged in close proximity to the discharge-pipes, all substantially as described and shown.

3. In a smoke-consumer, the combination with a combustion-chamber or fire-pot, of a series of discharge-pipes opening into the firepot at the top portion thereof, a cold-air duct communicating with the discharge-pipes and open at both ends, a series of' fan-jet tubes carried through the discharge-pipes and a steam-pipe commu nicatin g therewith and supplying steam thereto under pressure, and exhaust-ducts one communicating with the coldair duct from a point below thegrate and one or more exhaust-ducts communicating with the cold-air duct from the top portion of the combustion-chamber, all substantially as described and shown.

4. In a smoke-consumer, the combination with a combustion-chamber or fire-pot of the discharge-pipes D D, the cold-air duct B, open at both ends, the exhaust-duct D opening into the fire-pot above the grate and communicating with the cold-air duct, an exhaust-duct extending from a point below the grate and communicating with the cold-air duct formed of the pipes C, O, and C properly coupled together, the fan-jet tubes 6, e flattened at their respective ends and communicating with a steam-supply pipe and means for forcing steam through said steampipes under pressure, all substantially as described and shown.

5. In a smoke-consumer, a cold-air-supply duct, a series of discharge-pipes opening out of said cold-air duct and opening into the combustion-chamber, a steam-pipe extending into the cold-air duct, and a series of tubes with flattened nozzles extending from the steam-pipe and into the series of dischargepipes and a series of exhaust-tubes communicating with the combustion-chamber and the cold-air duct and arranged each one of the series alongside and in close proximity to the discharge-pipes.

In testimony whereof I aftix my signature in presence of two witnesses.

JOSEPH F. CODY.
